gpg: Fail decryption for AES etc message w/o MDC.
* g10/mainproc.c (proc_encrypted): Fail for modern messages w/o MDC.
--

This change turns the missing MDC warning into an error if the message
has been encrypted using a cipher with a non-64 bit block length cipher
and it is not Twofish.

We can assume that such messages are created by code which should have
been able to create MDC packets.  AES was introduced with 1.0.3 on
2000-09-18 shortly after MDC (1.0.2 on 2000-07-12).  We need to
exclude Twofish because that might have been used before MDC.

For whatever stupid reasons I once allocated only one memory area and
split that into PI and PI2.  This is actually a common pattern with
malloc but here we used a made up object size and do not take the
extra alignment required into account.  One of these not yet hit by
a (sig)bus PC/VAX hacker bugs.

Instead of trying to fix the alignment, it is better to use a second
calloc for the second struct.

It is in general a bad idea to use honor-keyserver-url but if Dirmngr

Dirmngr know about the use of this option and let Dirmngr tell use
whether TOR mode is active so that we can print a hint to disable that
keyserver option.

A future extension in gpgconf may disable that option directly but a
user may still override that and thus we better check.
